As temperatures soar on Friday, thunderstorms are expected to hit various parts of the UK, prompting heat-health alerts to be issued. Here are the details:

Thunderstorm Warnings

• South-west England and Wales: 00:00-13:00 on Thursday
• South-east England: 15:00 on Friday - 06:00 on Saturday
• Western England, Wales, and southern Scotland: 00:00-18:00 on Saturday
• Northern Ireland: Yellow weather warning for rain from 06:00-21:00 on Thursday

Some areas could experience heavy rain, with 10-20mm falling in an hour, potentially leading to flash flooding. Thundery showers will move northwards throughout the day, with Scotland likely to see less thunder on Thursday night.

Friday Forecast

Thunderstorms are predicted to hit south-east England and East Anglia, bringing 30-50mm of rain and a risk of surface water flooding. The recent dry spring could exacerbate the flooding. Hail, lightning, and gusty winds may also pose additional challenges.

Temperature Surge

Temperatures are set to soar in eastern England, with peak temperatures of 28-29C expected on Friday. A southerly wind will bring warm air from the near continent, where temperatures have exceeded 30C. Cloud cover in the afternoon, along with thunderstorms, will create a hot and humid environment.

Spring Records

The UK experienced its warmest spring on record, with Northern Ireland, Scotland, and Wales also seeing their sunniest spring. England had its second sunniest spring. The heat-health alert indicates a higher demand for health care services, particularly among vulnerable individuals and those over 65 with pre-existing health conditions.
